After years of false dawns, many of the world’s leading tech companies are now betting that quantum computers will start to outperform their conventional counterparts by 2030 – with a potentially huge impact on fields ranging from cryptocurrencies and financial services to drug discovery.
“It sounds really futuristic and I fully understand that,” says Gerald Mullally, CEO of Oxford Quantum Circuits, pointing to his company’s client base as a vote of faith in the technology’s potential. “Essentially it’s a bet that these companies are making that ‘this is going to happen, it’s going to matter and so the sooner we engage with it, the more practice we get.’”
But some scientists worry that the sheer power of the technology could endanger privacy and national security while others still doubt that useful machines can be made at all.
